V51I:
Volatile Distribution and Cycling in the Mantle I


Session ID#: 7967

Session Description:
The amount, distribution and speciation of volatiles (including H, B, C, N, S and halogens) in the Earth’s mantle are crucial for constraining melting and metasomatism, electrical, thermal and seismic properties, as well as geodynamics. How these volatiles transfer from the crust and the exosphere to the deep Earth and back, or whether some of them originate from primordial reservoirs, is critical to understanding volatile cycling through time and Earth’s planetary origin. We invite contributions that address these issues via natural samples, experiments or models from the scale of minerals to the whole planet. Projects centered on any tectonic setting and mantle depth (from the lower to the upper mantle) and geological time (Archean to present) are welcomed.
